>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.4.10
>            Reporter: Shil Sinha

> Example:
> {code}
> class Foo {
>     String pls
>     @groovy.lang.Delegate
>     Bar bar
> }
> class Bar { 
>     String pls        
> }
> assert new Foo(pls: 'ok').pls == 'ok'
> {code}
> Running the code above results in the following exception:
> {code}
> java.lang.NullPointerException: Cannot set property 'pls' on null object
> {code}
> Delegation of properties should behave the the same way as delegation of methods i.e. properties of delegates should not take precedence over properties declared in the owning class.
